3232New project CESSY funded by the ZIM initiativehttps://www.i-meet.ww.uni-erlangen.de/2018/02/new-project-cessy-funded-by-the-zim-initiative/
Mon, 12 Feb 2018 10:20:45 +0000https://www.i-meet.ww.uni-erlangen.de/?p=1065i-MEET has recently been granted a new research project called CESSY, which focuses on the development hybrid solar collectors which combine photovoltaic power generation with solar thermal hot water generation. Thereby, these devices have the potential of not only increasing the overall energy efficiency and of generating also an economic benefit. However, nowadays these devices are usually optimized with respect to only one of the tow technologies. In CESSY, i-MEET strives, together with an SME partner, which is specialized in thermal engineering, for developing a system which is optimized with respect to both its overall energy and economic efficiency.
CESSY is funded by the ZIM initiative (Zentrales Innovationsprogramm Mittelstand) of the Federal Ministry for Economic Affairs and will run throughout October 2019.

Sat, 25 Nov 2017 09:31:17 +0000https://www.i-meet.ww.uni-erlangen.de/?p=962The mineral perovskite is considered a miracle semiconductor in optoelectronics and especially in solar technology. Highly efficient, but so far hardly suitable for everyday use due to incompatible interfaces. I-MEET researcher Dr. Yi Hou is working on resolving the problem by creating a material system that allows the production of efficient and durable perovskite-based solar cells. With the help of special nanoparticles, he developed a generic process with which the boundary layers in the solar cell can be very precisely doped.

Since all processes take place at low temperature and from solution, this invention has the potential to revolutionize printed solar technology. Yi published the research results in the journal of Science. (doi: 10.1126 / science.aao5561, Full Text)

Perovskite is considered a particularly suitable semiconductor to convert sunlight into electricity. For example, the material is particularly easy to process. While standard semiconductors such as silicon are either melt-removed or deposited in high-vacuum systems, perovskite can be applied from the solution at normal room temperature, for example by means of printing and coating processes.

With a thin layer of tantalum-tungsten oxide (Ta-WOx) nanoparticles, Yi has now succeeded in further increasing the efficiency of the material – to a value of even 21.2 percent. This degree of efficiency has not yet been achieved by research for this component architecture. Ta-WOx/conjugated polymer multilayers offer a small interface barrier and universally form ohmic contacts with various scalable conjugated polymers. This work will stimulate broad interest, which is beneficial not only to perovskite photovoltaics but also to the conventional as well as the emerging photovoltaic technologies.

This hollow-sphere, which is a self-assembled structure of small particles, could have a great potential in catalysis application.

The results were presented at PSCO conference which was held September 18−20, 2017 in Oxford (U.K.) and highlighted in Editorial issue ACS Energy Letters.

Photovoltaics research at ANU spans the entire spectrum of solar electricity technologies—from solar forecasting, to fabricating high-efficiency PV, to integrating renewables with storage capacity into the grid. ANU has world-leading silicon solar cell research including advanced defect characterisation, surface passivation optoelectronics and the manufacturing of high-efficiency back-contact solar cells. We are also pioneering the exploration of nanostructures for photovoltaics, tandem silicon-perovskite solar cells and advanced PV optics.
Photovoltaics research at FAU has a strong material related fundament, linking multiple institutes from different departments and faculties (material science, chemistry, chemical engineering, computer science, physics). The cooperation with various research centers, among them the Bavarian Center for Applied Energy Research (ZAE Bayern) completes the value chain from materials to devices over processing to photovoltaic systems and applications and covers many different solar cell technologies, including organic, hybrids, perovksites but also chalcopyrites and silicon. Research at i-MEET, the institute for materials for electronics and energy technology, has a long time expertise on low temperature solution processing of photovoltaics.

The research will be directed by Dr. Heping Shen (ANU) and by Dr. Yi Hou (FAU).

Tue, 19 Sep 2017 15:02:36 +0000https://www.i-meet.ww.uni-erlangen.de/?p=898Light-weight and stretchable, organic photovoltaics offer unique integration prospects. Now, a recent report from Someya in Nature Energy (doi:10.1038/s41560-017-0001-3) reported a breakthrough and showed that organic solar cells and modules can also be washed while maintaining good photoconversion efficiencies. Nature Energy invited us to discuss the relevance on this finding for the OPV roadmap. A focus on integrated portable solutions provides a strong marketing concept for OPV technology. We believe that washable and wearable solar cells will constitute a unique selling point for OPV modules, complementing flexibility and stretchability, in complete opposition to today’s more traditional PV technologies such as silicon. For these applications, power (W per m²) and costs (€ per m²) are not the right benchmarks. Instead, the performance of the solar cell must be sufficient to provide application-specific functionality — washability, for example — and the costs must not be a barrier to market penetration. Therefore, we believe that the industrial OPV roadmap is intrinsically different from those for inorganic and hybrid PV technologies, including that of perovskite PV.
